Wirksamkeit von Katalysatoren unter Bedingungen der mechanischen Bearbeitung

Mechanochemical Methods

“…The catalytic reaction [126] was found to take place only during the treatment process. As shown by Lischke and Heinicke, the hydrogenation of benzene on Ni metal under mechanical exertion took place even in the presence of the strong catalyst poison thiophene if corundum particles were added to Ni [127,128]. Studies at elevated temperature comprised the oxidation of SO 2 on V 2 O 5 in a vibratory mill at 350-500 • C [101].…”

Mechanocatalytic hydrogenolysis of benzyl phenyl ether over supported nickel catalysts

“…While the mechanocatalytic hydrogenation of benzene over nickel in a vibratory ball mill was reported as far back as 1963, 36 studies on reductive mechanocatalysis with gaseous hydrogen have been sparse. 37 The methanation of CO 2 over Ni/Fe/Ru on MgO catalysts 38 and LaNi alloys 39 and of CO over mixed FeCo and MgNi catalysts 40 have been demonstrated.…”
